不同类型穗条嫁接对油茶芽苗砧嫁接苗生长发育的影响研究

The Effect of Different Scions Grafting for Bud-Understock Graftings Growth and Development of Camellia Oleifera Abel.

摘要:

摘要：对油茶接穗木质化程度和砧木与嫁接苗成活率及其生长的相关性进行了研究，结果表明：①刚木质化、半木质化、全木质化3个试验处理对嫁接苗成活率、抽梢率、高生长、地径差异极显著，接穗刚木质化处理成活率94.67%、抽梢率92.00%、高生长6.19 cm效果较好；②砧木采用胚芽和胚根嫁接对嫁接苗成活率、抽梢率、生长势差异显著，胚芽为砧木嫁接效果较好。结合实际生产，在油茶芽苗砧嫁接时，建议选取刚木质化或者半木质化的枝条和带有胚芽砧木为好，尽量不采用胚根嫁接。

Abstract:

Abstracts: the choose of the lignification extent of scion and rootstock,grafting seedling suvival rate and growth are taken as research object. The results showed that①the survival rate, growth rate, height and basal diameter of the three treatments are significant difference among, a little lignification, half-lignification, full-lignification.The effect of a little lignification treatment was the best, the survival rate, growth rate and basal diameter are respectively 94.67%, 92.00%, 6.19 cm；② It is significant difference among the survival rate, growth rate,the seedlings grafted by germ and raddicle. That the seedlings were grafted on the germ was better. In production, a little lignification and half-lignification were taken to graft, but it is suggested to not use raddicle to graft.
